Nitro OBD2 / Eco OBD Chips

Fuel Pro Max Chip

From our Analysis:

From our research and review, it is our opinion that the NitroOBD / EcoOBD OBD module performance chip is a scam. It may also cause ECU damage, as reported by some users on the net, so we suggest avoiding it at all costs. It is a nice light show at best, damaging at worst. You want to pass on this one!

Scam!

Company Profile

The manufacturer is a company called ‘Nicolay’, according to the packaging. However, we were unable to find a website or real company under this name. Perhaps it is a generic brand name?

Cost

The cost averages from the $3USD range, up to $25USD, depending on the source, eBay, Aliexpress, Amazon, etc. The cost is a very suspicious factor to us, as no genuine tuning product can be manufactured this cheaply.

Product Appearance

The OBD tuner modules come in four different colors, and they claim each is for a different type of engine:

2. 3. Insert the key into the ignition and twist the key to the first stage. (Do not start the car) 4. Press the reset buttom for about 5 sec. After releasing the buttom, just wait for a while about 30-54 sec. (NitroOBD2 Chip Tuning Box will communicate and establish connection with ECU) 5. Start up the engine. 6. NitroOBD2 Chip Tuning Box will recognize your vehicle and your driving habits, after around 200 km/150 miles driving and thus NitroOBD2 Performance Chip Tuning Box will adjust itself to match your car perfectly for more fuel saving.

The instructions claim to have vehicle maps onboard to allow the device to optimize the vehicle performance when connected to the OBD port.

Internal Analysis

We purchased a few of these modules from different sources, and ended up with a few different circuit boards inside:

Aliexpress even shows three different versions of circuit boards:

Nitro-OBD-PCBs-Aliexpress

They show a checkmark beside the first one, while the others have an ‘X’ beside them. While they say the first is best, the middle board is actually the original version, and was seen in the earliest NitroOBD modules. Why make the first one appear to be the best? Answer: Simple – it is the one they are tying to sell you!

The first circuit board is built around a PIC16F59 IC:

Nitro-OBD

Right away we see a problem here, because if one pulls the datasheet for the PIC16F59 IC, we can see from the manufacturer, Microchip, that this chip has a maximum program memory size of 3KB:

From several searches, we verified that ECU maps for a vehicle will be at least 20KB or larger PER MAP! This is way too large for the PIC16F59 IC to contain. So, if this is the case, there are no genuine vehicle maps onboard the module. What can be stored in such a small 3KB sized space then? We have our own suspicion.

The second circuit board is built around a hidden IC on the back of the PCB:

NITRO-OBD-hidden-IC

After deeper inspection, we see that this chip is a STM8S003F3, a value line IC manufactured by ST. The datasheet shows this IC has only 8KB of program memory, also too small for genuine vehicle maps

Operation

We connected the Nitro OBD module to our 2012 BMW 530i 3.0L L6 as shown in the instruction sheet and lights began to blink:

Another feature that confirms our suspicions was the fact that the lights blinked in an all too familiar pattern – exactly the same as the Nitro OBD scam chip did. It looks like our suspicions were correct.

We followed the instructions and drove at least 200+ miles to give it the benefit of the doubt, and…… nothing. No power increase, no mileage increase. We did, however, see a neat light show!

Analysis

It is clear from our analysis so far that the NitroOBD module does not have the physical capacity to hold real vehicle ECU maps. 3KB of memory IS large enough for a light blinker program, however, and we believe this is exactly what it truly is – a light blinker in different colored cases. The circuit appears to monitor the pins from the OBD port and the small microprocessor blinks the lights when activity is detected, giving the appearance of the chip’s operation. While some users online claim to have seen small gains in pickup or fuel economy, we believe this is due to either the placebo effect or another vehicle / environmental factors. While we did not get any error codes set by our NitroOBD module, others claim it does set error codes, and if so, this is a major red flag.

The second issue is the claim that it fits SEVERAL different vehicles – this is not possible, even for one vehicle, with such a small 3KB program capacity.

The third issue is that the same circuit is used in all different colored cases we opened – red, yellow, green, blue – it did not matter. We found the same boards as in the yellow version, and, the same ICs.

Conclusion

From our research and review, it is our opinion that the NitroOBD / EcoOBD module performance chip is a scam. It may also cause ECU damage, as reported by some users on the net, so we suggest avoiding it at all costs. It is a nice light show at best, damaging at worst. You want to pass on this one!

Having read your article regarding nitro, i bought one a few months ago just as a gadget, however your article made a lot of sense, I suppose a lot of folk want to save money where their pride and joy is concerned but not at the cost of damaging the ecu, the one I bought has been binned, I was sceptical when I bought it and having read your article confirmed it.

I put one in my silverado 5.3 and i thought i would have worked well and today i took it out and my trucks maping is all screwed up then i came up apon your article so i wonder is there a way to bring back my original maping of my truck? Thanks

I’m not sure where you are getting your info, but great topic. I needs to spend some time learning much more or understanding more. Thanks for excellent info I was looking for this information for my mission.

I have had the (PerformanceChipName) in my Volvo c70 for 76k miles with no problems and gained estimated 25 horsepower with drop in filter and exhaust. Now I installed (PerformanceChipName) in my Equus 3 weeks ago, so far, no problem, enough power to break the wheels loose est. 27 lb. Of torque and 29 hp. Gain on a 385hp v8.😉
